Ornithology in Sol#

Ornithology in G#: Charlie Parker's bebop head on How High the Moon runs the cycle of fourths with surgical precision. Bebop and Bebop Major scales are the core language — navigate the ii-V-I sequences in multiple keys without hesitation. Chords: G#Maj7 – G#m7 – C#7 – F#Maj7 – F#m7 – B7 – E7 – A#m7b5 – D#7 – Cm7 – F7 – A#m7.

Ornithology in Sol#

G# major (or Ab) lives at fret 4 on the low E string. All chords require barre technique, making it less common in guitar-centric songwriting but standard in piano-driven pop. Guitarists often use a capo to access friendlier shapes. G# is a intermediate-advanced-level key on guitar because the open G string is a half step below the root, creating dissonance — avoid letting it ring. Expect to rely on barre chords throughout, which builds hand strength and unlocks the entire fretboard.

Voice Leading

The bass line moves through G# to G# (ascending unison), G# to C# (ascending perfect fourth), C# to F# (ascending perfect fourth), F# to F# (ascending unison), F# to B (ascending perfect fourth), B to E (ascending perfect fourth), E to A# (ascending tritone), A# to D# (ascending perfect fourth), D# to C (descending minor third), C to F (ascending perfect fourth), F to A# (ascending perfect fourth). The root motion by larger intervals (fourths and fifths) gives each chord change a strong, decisive character. When the progression loops, the bass returns from A# to G# by whole step.

Scales for Improvisation

G# major pentatonic works because every note is either a chord tone or a safe passing tone — there are no avoid notes. For soloing, this means you can play freely without clashing. Over dominant seventh chords, G# Mixolydian adds the flat seventh for an authentic blues-rock edge.
